the space between the fifth and seventh veins ; the tliird and 

 broadest band iuchides the cross-veins, lying mainly beyond 

 them, it is broadest in the middle of the wings and extends 

 to the apex of the discal cell ; the fourth band occupies the 

 whole of the apex of the wing. The prsefurca arises about 

 the middle of the wing, and is obtusely angulated near its 

 base. Marginal cross-vein considerably beyond the fork of 

 the radial vein and near the termination of the subcostal. 

 Small cross-vein almost in a line with base of submarginal 

 cell, situated at the base of the discal cell. First posterior 

 cell very slightly contracted at apex. Discal cell very 

 narrow, tapering almost to a point at the base. Sixth vein 

 slightly sinuous. Wing-margin indented at the terminations 

 of the sixth and seventh longitudinal veins. Great cross- 

 vein a little beyond the base of the discal cell. Hnlteres 

 black, apical half of knob white. Abdomen with the first 

 segment and the base and sides of the second shining blue- 

 black, the remainder of the dorsum purplish brown, somewhat 

 shining; venter brown. 



Length of body 3-5 mm. ; wing 4 mm. 



The uniform bkie-black colour of the dorsum of the thorax 

 will distinguish this species from any other in the genus. 

 It is the smallest species, except for T. polita.

Head greyish ochreous, with black bristles ; tips of palpal 

 and first antennal joints darker; second antennal joint 

 entirely black. Thorax : prothorax dark brown at the sides, 

 greyish ochreous in the middle, with a dark median line 

 ])Osteriorly ; a tuft of black bristles on each side in front. 

 Mesonotum with the ground-colour cinereous above, ochreous 

 at the sides ; two distinct blackish-brown bands, closely 

 approximated in front, somewhat divaricated behind, con- 

 tinued as far back as the suture as narrower and lighter 

 bands ; outside these on each side is a narrow, indistinct 

 brown band, starting from a small pale ochreous depression 

 near the front margin ; behind the suture are two brown 

 spots; two distinct rows (one on each side of the median 

 line) of black bristles. Scutellum greyish ochreous, with 

 two black bristles. Me t anotum dark hr own, P/ewr« greyish
